CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 267,210, dated November'7, 1882.

Application filed August 18, 1882. (No model.)

To all whom it may concern Be it known that I, IRVIN M. JACOBS, of EastGreenville, in the county of Montgomery and v State of Pennsylvania,haveinvented certain new and useful Improvements in (Jar-Couplings; andI do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to makeand use the same, reference being badto the accompanying drawings, which form a part of this specification,and in which Figure l is a perspective View of my improved car-coupling.Fig. 2 is atop view, and Fig. 3 is a longitudinal sectional view.

.Qorresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to automatic or selfacting car-couplings; and itconsists in certain improvcments'in the construction of the same whichwill be hereinafter fully described, and particularly pointed out in theclaim.

In the drawings hereto annexed, A represents the draw-bar, which issecured under the car, and provided with a recess, B, to receive therear end of the stem or shank O of the draw-head, which is pivoted insaid recess upon a vertical bolt, D, which passes through a slot, E, insaid stem or shank, which is thereby enabled to move longitudinally. Inthe recess. B is placed a coiled buffer-spring, F, serving to force thedraw-head,between the shank O of which and said spring a washer, W, isinterposed, automatically in a forward direction.

The draw-head G, at the front end of the stem or shank O, isarrow-shaped, as shown, or formed with hooks H, extending laterally toboth sides. The front end of the draw-head G has a horizontal mouth orrecess, 1, to receive a coupling-link when it becomes necessary tocouple a car having my improved coupling with one having theold-fashioned pin and link. to receive the coupling-pin.

K K are flat springs, secured firmly to the sides of the shanks G of thedraw-head by means of bolts L, terminating at their outer ends in eyesM. The rear ends of the springs K bear against the sides of the draw-barA, as clearly shown in Fig. 2 of the drawings. The eyes M serve for theattachment of chains leading to the sides of the car, to be used inuncoupling; or levers may be pivoted to the ends of the car, or to theplatform, and have their lower ends extended down into said eyes Mforthe same purpose.

The operation of my invention will be readily understood. When the carscome together the hooked draw-heads engage each other, the draw-headsand shanks swinging upon the bolt or pivot D to permit such engagementto take place. In order to uncouple, either draw-head may be drawn asideto release it from the one of the opposite car.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, with thearrow-shaped draw-head G H, pivoted at the outer end of the draw-bar A,of the fiat springs K K, fixed on opposite sides of the draw-head andbearing with their free ends against the sides of the draw-bar,substantially as and for the purpose herein shown and specitied. I

In testimony that I claim the foregoing as my own I have hereuntoaftixed my signature in presence of two witnesses.
